Efficiency of music therapy in reducing propofol requirements in patients scheduled for urologic procedures under sedation

Abstract

Introduction: Urological procedures are useful toolsin patients with urethro-vesical pathology and the use of hypnotics such as propofol are necessary for their performance. Music therapy has proven to be a non-pharmacological tool capable of reducing the pharmacological requirements  during the procedure, maintaining levels of sedation and greater comfort after the procedure. Objectives: In general, to evaluate the efficacy of music therapy for the reduction of propofol requirements in patients scheduled for urological procedures under sedation, among the specific ones, the evaluation of propofol requirements, comparing levels of sedation through BIS, recording of hemodynamic parameters and evaluation of comfort. Methods: clinical, prospective, cross-sectional study. Prior authorization from the Ethics Committee, the study was conducted with patients from the Urology service of the CMDLT, undergoing urological procedures under sedation, distributed into 2 groups, music and control, receiving standard sedation with propofol (1 mg/kg) with rescues of 20 to 30 mgs according to demand. Group M received music 10 minutes prior to the procedure , and Group C did not received. The total dose of drug used in both groups was taken into account, as well as hemodynamic parameters and sedation levels by BIS. At the end of the procedure, the Likert Scale for patient comfort was evaluated. Results: 40 patients participated in total. There was a statistically significant difference in sedation levels, propofol requirements and comfort between Groups M and C. Conclusion: Music therapy is capable of reducing propofol requirements and maintaining adequate levels of sedation and generating greater post-procedure comfort.
